Complex optical study of V sub(2)O sub(5)-P sub(2)O sub(5)-B sub(2)O sub(3)-GO glass systems by ultraviolet-visible spectroscopy

In the present work, complex optical parameters such as absorption, extinction coefficient, refractive index, optical conductivity, real dielectric constant and imaginary dielectric constant of V sub(2)O sub(5)-P sub(2)O sub(5)-B sub(2)O sub(3)-GO glass systems have been studied. The melt quenching method was adopted for the preparation of V sub(2)O sub(5)-P sub(2)O sub(5)-B sub(2)O sub(3)-GO glass systems. The conformation of glassy phase in sample was done through X-ray diffraction analysis. The optical parameters were analyzed using ultraviolet-visible spectroscopy. The dispersion of graphene oxide in V sub(2)O sub(5)-P sub(2)O sub(5)-B sub(2)O sub(3)-GO glass systems significantly affects the complex optical parameters. The extinction coefficient, real dielectric constant and imaginary dielectric constant gradually increase after 225-600 nm. Whereas, optical conductivity shows gradual increase around 225 nm.
